Schubert would be especially amazed to learn that he has come to be regarded as a great symphonist. Of all the genres in which he excelled, these fared the worst during his life. His first two were written for his school orchestra and the next four for an amateur group he was able to assemble, all intended to be heard once and then forever forgotten. Written in his teens, they gleam with dewy innocence, reminiscent of Mozart's juvenilia, with only the barest hint of an incursion of strife. Among his most enduring from that period we can single out the Fifth, a buoyant package of joy.
